DESCRIPTION:Arbuscular  mycorrhizal  (AM)  symbiosis  is  a  mutually  ben
 eficialinteraction  between fungiand plants\,  contributing  to  plant  fi
 tness  and  global  nutrient  cycles.Two  paralogous /hydrolase rece
 ptorproteins\,Arabidopsis KARRIKIN  INSENSITIVE  2  (KAI2)and DWARF  14(D1
 4)\, recognize butenolides\,  the  smoke  compound karrikinsand the  plant
   hormone strigolactones\, respectively.Strigolactones induce hyphal branc
 hingofAMfungiin the rhizosphere while  rice DWARF14-LIKE   (D14L)\,   the 
   homologue   of   KAI2\,   is   indispensable   for   AM   symbiosis esta
 blishmentas shown by thecomplete block of AM symbiosis in d14lmutants\, su
 ggesting an essential  role  duringpre-symbiotic  communication. The promo
 ter  of D14Lis  expressed  in  the vasculature and the D14L protein shows 
 nucleo-cytoplasmic localization\, raising the questionsof how  fungal  per
 ception  in  the  rhizosphere  is  mediatedand  whether  both  the cytosol
 ic  andthenuclear pools are necessaryfor D14L signaling.
